Controller Termination - Integra MZA-4.7 Instruction Manual

Controller Termination

White/Blue
The recommended wiring and color scheme is shown in Fig 2.
Use the Standard 568-B color code for the CAT5E termination to the Controller – see Table 1. Although it is possible
to daisy chain controllers we recommend "home runs" of CAT5E cable with a maximum cable length of 200m.
Note: Some IR receivers have an Amplifier On indicator, their "On" terminal should be connected to the zone's AMP
ON output not to the controller interface ports "Data" terminal.
